Onigiri~ Posted December 27, 2011 Report Share Posted December 27, 2011 MATHL/PF/M12/N12/M13/N13anyone know what are we supposed to do for 'use various values for a and b to generate pairs of functions y1 and y2.' Reply Link to post Share on other sites More sharing options...
ibmath604 Posted December 30, 2011 Report Share Posted December 30, 2011 what exactly are we supposed to do in 'use various values for a and b to generate pairs of functions y1 and y2.also,can anyone tell me what they got their y2 as?thanks Reply Link to post Share on other sites More sharing options...
eleez Posted January 13, 2012 Report Share Posted January 13, 2012 the last question about the quartics functions can be answered by simply applying the general formula you came up with for the quadratics and the cubics functions to the quartics functions it applies in the same ways to the quartics as it does to the quadratics and cubics gd luck Reply Link to post Share on other sites More sharing options...

o0IB Surviver0o Posted January 19, 2012 Report Share Posted January 19, 2012 i need help too...for part B, 2nd last point "on a labelled diagram"how to differentiate one of the zero to be the intersection and the other two are the complex roots?

firewater476 Posted January 21, 2012 Report Share Posted January 21, 2012 HELPP. I am also stuck on the 4th question of part B: write a general statement about the functions y1, y2 and ym. Does this just mean the same thing as express y2 in terms of y1 and ym? coz if it is, then I am already asked that in the 3rd part of part B. also , there is no general statement for quadratics, only the express y2 in terrms of y1 and ym. so is this the general statment? and if so, how do i prove its correct?

Ivanna Posted January 27, 2012 Report Share Posted January 27, 2012 does anyone know what should be done in the "use various values for a and b to generate pairs of functions y1 and y2. thanks in advance Reply Link to post Share on other sites More sharing options...
iHubble Posted February 3, 2012 Report Share Posted February 3, 2012 Just label your complex root in space. The X and Y axis are only for real value of X and Y. Do not use an Argand diagram, a lot of people used one in my class and lost a whole bunch of points. Reply Link to post Share on other sites More sharing options...
3.46q2 Posted February 4, 2012 Report Share Posted February 4, 2012 Well, just graph y1, ym and y2 on the same graphic. Then, identify every roots and intersection points. You'll know the relation between the three main functions as you compare them. do you have to draw it on an argand diagram, if not how do you label the complex roots?

Dinstruction Posted February 10, 2012 Report Share Posted February 10, 2012 I just want to confirm, but ym is expressed in terms of x, a, and b, right? Reply Link to post Share on other sites More sharing options...
SRPirate14 Posted February 18, 2012 Report Share Posted February 18, 2012 Hey, I need help on illustrating how the zeros of y2 may be helpful in the determination of the real and imaginary components of the complex zeros of y1 on the last bullet point of part A. Does anyone how to go about solving this? and also what did you guys get for the expression of y2 in terms of y1 and ym in part A as well?

dwaidai Posted February 22, 2012 Report Share Posted February 22, 2012 the general statement is y2=-y1+2ym Reply Link to post Share on other sites More sharing options...

morry99 Posted March 2, 2012 Report Share Posted March 2, 2012 what is the general statement for part b cubic polynomials? is it the same as "express y2 in terms of y1 and ym" thankyou Reply Link to post Share on other sites More sharing options...
